Happy new year, @erichkeane! Here's a summary of actions taken in response to 
RFC feedback and review feedback:

* We no longer accept different integer sizes (`%hhi` and `%i` are now 
incompatible, for instance), as 
[agreed](https://discourse.llvm.org/t/rfc-format-attribute-attribute-format-like/83076/12).
* Removed support for `scanf`, as Aaron brought up a few things I wasn't clear 
about, and I don't need it, and it wasn't really part of the RFC, and it's 
probably better to leave it alone until somebody who knows scanf well wants to 
take it over.
* Documentation was updated to clarify these 2 points.

Notably, I didn't change the handling of signedness mismatches (diagnostics are 
controlled by `-Wformat-signedness`): I understood this was OK when you said 
the RFC was good as it sat, without an agreement on changing this.

I recommend [reviewing with 
`?w=1`](https://github.com/llvm/llvm-project/pull/116708/files?w=1), as it 
brings down the size of the SemaChecking.cpp diff a good amount (down to 550ish 
lines).
